Example code:

pawn Код:

new muted[ MAX_PLAYERS ];
CMD:mutemeforaminute( playerid, params[ ] ) {
    SetTimerEx( "unmute", 60000, 0, "i", playerid ); 
    muted[ playerid ] = 1;
    return SendClientMessage( playerid, -1, "You have muted yourself for a minute. " );
}

public OnPlayerText( playerid, text[ ] ) {
    if( muted[ playerid ] == 1 ) {
        SendClientMessage( playerid, -1, "Can't talk while muted! " );
        return 0;
    }
    return 1;
}

forward unmute( playerid );
public unmute( playerid ) {
    SendClientMessage( playerid, -1, "A minute has passed, you have been unmuted. " );
    muted[ playerid ] = 0; 
    return 1;
}

public OnPlayerDisconnect( playerid, reason ) {   
    muted[ playerid ] = 0; 
    return 1;
}

I think you can figure the rest yourself. You haven't provided any code, therefore we can't help you.
